Hi Bill, You, of course, know exactly what the humidity was at the previous tuning? And, of course, it had not changed? And you used the same measuring device on both occasions? The flat treble can easily be accounted for by lower humidity. Your analysis is flawed by your *own* words <snip> "I used my own aural ET as a reference tuning.
